SOAP Basic Auth, Empty in RAW

Hi!

I'm sending a SOAP:ENVELOPE-request using SoapUI with basic authentication using SoapUI's Auth-tab. This works great but I can't see what my header looks like in the RAW-tab. It's just empty.

How do I generate my header? I followed the steps in this guide: http://www.soapui.org/SOAP-and-WSDL/aut ... uests.html

Best regards,
Kim
